Fine Control of Cooling Fan Speed

[blex-max]

Is your feature request related to a problem?

I get the best mix of print quality and performance when running my cooling fan at about 50% of max, however dropping my fan to this speed gives me a little more ooze on travel moves. This isn't a problem, except on top surface skin layers where I tend to get unsightly blobs where I have a complex top surface that requires a few travels while doing the skin infill.

Describe the solution you'd like

I'd like to be able to define fan speeds for layer types, e.g. top/bottom fan speed, or better yet top skin fan speed. I know I'm not the only person to have requested this but I wanted to add my voice to the many.

Describe alternatives you've considered

I could tune retraction/zhop to try and minimise these blobs on top surfaces but I'm otherwise happy with my settings and I would rather have control of the fans.

Affected users and/or printers

I run larger nozzles, which I have found are more sensitive to part cooling and as we all know have more ooze! I'm having this specific issue on a modded Ender 3 pro with a 0.6mm nozzle with some admittedly lower quality filament. Nevertheless, I think it'd be a valuable addition to Cura.

This is similar to #10017 which is for fan control by layer as opposed to this request for fna control by "Type". This could be added as an optional method.

More precisely even, I'm closing this as duplicate of #5140.
